Astudent wanted to see what the affect of temperature is on glow sticks. he activated three glows sticks and put one in hot water, one in cold water, and one in room temperature water. he rated how “bright” each glow stick was on a scale of 1 to 10. what was the dependent variable in his experiment? a) how bright the glow sticks were. b) water temperature c) amount of water

A) how bright the glow stick were

because how bright the glow sticks are is what is being tested and measured in the experiment. so that makes it the dependent variable. it’s depending on the amount and temperature of water which the scientist can change.. (independent variable)

For cyclohexane compounds drawn in a chair conformation:   -axial bonds are vertical  -equatorial bonds are parallel to two bonds within the ring.  thus, as i assume the chair conformation is drawn:   -the x group is in an axial position, as are the five other vertical bonds.  -three axial bonds are on the top face of the ring  -the other three axial bonds are on the bottom face  the position of the second substituent on each ring carbon is equatorial.  gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other.  drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1.  click this link and watch some academic videos that may you more understand the topic
